flamaofizm United States Patent INCINERATOR George V. Thompson, Albuquerque, N. Mex.

Application November 21, 1952, Serial No. 321,915

6 Claims. (Cl. 110-18) This invention relates to new and useful improvements and structural refinements in incinerators, particularly incinerators of the domestic variety which are used outdoors for burning trash, vand the principal object of the invention is to provide an incinerator with smoke eliminating means so that the smoke is not objectionable to neighbors of the home where the incinerator is used.

The above object is achieved by utilizing hot air passing through the smoke stack of the incinerator for supporting or assisting combustion in the incinerator, thereby resulting in combustion at higher temperatures with very little smoke, if any, results.

Some of the advantages of the invention reside in its simplicity of construction, its eflicient operation and its adaptability to expeditious and economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention;

Figure 2 is a vertical sectional view thereof, the same being taken substantially in the plane of the line 22 in Figure 3;

Figure 3 is a horizontal sectional view, taken substantially in the plane of the line 3-3 in Figure 2',

Figure 4 is a top plan view of the invention on a reduced scale; and,

Figure 5 is a perspective view of the fire pot or burner pot used in the invention.

Like characters of reference are employed to designate like parts in the specification and throughout the several news.

Referring now to the accompanying drawings in detail, the invention consists of an incinerator which is designated generally by the reference character and embodies in its construction a vertically elongated, substantially cylindrical jacket 12 accommodating a foraminous, cylindrical burner pot 14, the latter being disposed eccentrically in the jacket and in spaced relation therefrom, so as to afford a chamber 16 between the jacket and the pot, as is best shown in Figures 2 and 3.

A plurality of horizontal bars 18 extend transversely through the jacket 12 and support the pot 14 which is removably positioned thereon, the pot 14 preferably being provided with suitable handles 20 so that it may be conveniently installed and removed.

In addition, a rod 22 extends transversely over the jacket 12 above the bars 18 and is provided with a substantially semicircular intermediate portion 22a, the latter extending partly around the circumference of the pot 14 and afiording a seat for the pot, so as to prevent the pot from shifting on the bars 18.

The bottom portion of the jacket 12 is provided with a pluraltiy of air inlet apertures or openings 24, as shown.

A smoke stack 26 surmounts the jacket 12 and includes an upper, tubular portion 26a and a lower frusto-conical 2,760,451 Patented Aug. 28, 1956 base portion 26b, the latter having an out-turned'flange 28 at the base thereof.

This flange is connected by a hinge 30 to the upper edge of the jacket 12, so that the entire smoke stack 26 may be swung to one side as indicated by the dotted lines 32 in Figure 2. In that position of the smoke stack, the interior of the jacket 12 becomes accessible for the purpose of installing or removing the pot 14. The smoke stack 26 is supported in its laterally swung position by means of an angulated brace 34 which is rigidly secured to the jacket 12 and extends upwardly and outwardly therefrom, susbstantially as shown.

A handle 36 is provided on the flange 28 of the smoke stack for the purpose of operating the same, and also, a suitable screen 38 is provided in the smoke stack between the portions 26a and 26b.

Finally, the invention contemplates the provision of a duct 40 which is in the form of a flexible tube and extends downwardly from an upper portion of the smoke stack 26 to an intermediate portion of the jacket 12, wherein it communicates with the chamber 16.

The flexibility of the conduit or duct 40, of course, will permit the smoke stack 26 to be swung laterally as shown in Figure 2, at 32, and when the apparatus is in operation, hot air passing through the smoke stack 26 will be drawn through the duct 40 into the chamber 16 and will assist the combustion in the fire pot 14 so that the combustion will take place at a comparatively higher temperature and little smoke, if any, will result.

After repeatedly experimenting with the invention, I have found that when dry material is being burned, no smoke results therefrom. However, if the material being burned is somewhat damp or moist, a little amount of smoke will be produced. This small amount of smoke, of course, is not objectionable, since it is far less than would otherwise result if the material were burned in a conventional incinerator.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

What is claimed as new is as follows:

1. In an incinerator, the combination of a vertically elongated jacket, a foraminous burner pot mounted in said jacket and spaced therefrom to provide a chamber between the jacket and the pot, an upwardly extending smoke stack including a frusto-conical base portion hinged to the upper portion of said jacket at one side thereof to swing over and with its base in registry with the upper end of said jacket whereby to form a closure for the upper end of the jacket, and a flexible conduit in communication with the interior of and extending downwardly from the upper end portion of said smoke stack and communicating with said chamber.

2. In an incinerator, the combination of a vertically elongated jacket, a foraminous burner pot mounted in said jacket and spaced therefrom to provide a chamber between the jacket and the pot, an upwardly extending smoke stack including a frusto-conical base portion hinged to the upper portion of said jacket at one side thereof to swing over and with its base in registry with the upper end of said jacket whereby to form a closure for the upper end of the jacket, and a flexible conduit in communication with the interior of and extending downwardly from the upper end portion of said smoke stack and communicating with said chamber, and means for removably supporting said pot in said jacket.

3. In an incinerator, the combination of a vertically elongated jacket, a foraminous burner pot mounted in said jacket and spaced therefrom to provide a chamber between the jacket and the pot, an upwardly extending smoke stack including a frustoconical base portion hinged to swing over and with its base in registry withthe upper end of said jacket whereby" to form a closure for the upper end of the jacket and a flexible. conduit in communication with the interiorof and extending.. ..downwardly from. the upp nd p rtion. of said. smokes aek' and com municating with said chamber, the lower portion of said jacket being provided with airjinlet openings.
